Abstract
A catalyst composition is prepared by dissolving a suitable oxygen containing compound of a Group VIB metal (preferably Mo), a suitable compound of a Group VIII metal (preferably Ni) and phosphorous acid in water, mixing this solution with an alumina containing support material, and calcining this mixture. This catalyst composition is used primarily for hydrotreating of hydrocarbon feed stream, which contain nitrogen and sulfur impurities, particularly heavy cycle oils.
